1
85 VAC to 135 VAC or 170 VAC to 265 VAC, fixed load.
2
The amount of change that occurs when the load is changed from no load to rated load (rated output
power/rated output voltage) with rated output voltage. The value is measured at the sensing point.
3
The amount of time required for the output voltage to return to a value within “rated output voltage ± (0.1%
+10 mV).” The load current fluctuation is 50% to 100% of the maximum current with the set output voltage.
4
When the measurement frequency bandwidth is 10 Hz to 20 MHz.
5
When the measurement frequency bandwidth is 10 Hz to 1 MHz.
